In this research, we study how task and KMS fit influences on KMS performance in large corporations during its practical use. Based on the task-technology fit theory and information system success model, we developed a research model by considering the characteristics of KMS for supporting tasks. We try to verify how individual traits, task traits, and KMS Units affect task-KMS fit and how task KMS fit influences on KMS performance. We surveyed 212 employees who were using KMS and working for the large-sized manufacturing firms. We analyzed the collected data from LISREL 8.54 for Windows, and found the following significant results. First user satisfaction is increased when KMS provides knowledge to help to perform task rather than KMS' functionality. Second, user satisfaction is increased when KMS is suitable for performing task Hence, we verified task-KMS fit is an antecedent of user satisfaction. Third, task-KMS fit and user satisfaction have significant impacts on KMS performance. And user satisfaction affected more heavily on KMS performance than task-KMS fit did. As a result, we realized an individual performance can be improved when task KMS fit is high and, consequently, user satisfaction is increased. Forth while the usefulness of task-KMS fit is demonstrated, causal factors such as individual traits, task traits, and KMS traits significantly affect task-KMS fit. Formalization and knowledge trait we significant in enhancing user satisfaction, but KMS self-efficacy, autonomy, md system trait are not. These results indicate that task-KMS fit variable is useful as a measure of KMS performance as well as that of user satisfaction. Based on these results, we conclude that when KMS supports task activity, performance can be significantly improved by coordinating the task with KMS.

The aim of this study is to analyze how both the quality of KMS (Knowledge Management System) and its organizational factors have effect on the utilization and user satisfaction in the defense sector. This study has verified the effects and identified the main factors affecting KMS performance measures. The nature of KMS quality and its organizational characteristics were deduced from previous research results, and a questionnaire survey was conducted on 250 KMS users in the defense sector on the performance of KMS based on the time spent on KMS and the overall satisfaction through which the hypothesis was verified. This study has made several contributions in the fact that it had provided the opportunity to analyze which factors have impact on knowledge management performance in the defense sector and the utilization and users' satisfaction of KMS reflecting the viewpoint of the organizational characteristics of the military, while studying the factors which can affect the performance for knowledge management.

In order to manage organizational knowledge efficiently, Knowledge Management System(KMS) is considered as mandatory. This study aims at developing a KMS performance model to predict user satisfaction as well as KMS usage, considering the unique features of KMS. By analyzing 261 surveys with LISREL, we found that community of practice(CoP) characteristics - participation and interactivity among users - significantly affects KMS user satisfaction. This implies that the development of KMS should focus on facilitating users' interactivity and participations such as CoP activity, which differs from the general information system context. We also found that KMS usage is influenced by CoP interactivity, not by CoP participation, and that KMS usage as well as user satisfaction leads to user performance. Interpretations and implications of the findings are discussed.

In this research, we analyzed empirically whether the valuation and compensation factor being moderating variable played the role of adjuster between KMS adoption factor(organizational factor, knowledge Informational factor, user factor) and business performance. The results of this research are as follows. First, The valuation and compensation factor affects the usage of KMS in case of organization's flexibility, trust, suitability of knowledge, degree of functional provision and perceived benefit. But it does not affect the usage of KMS in case of easiness of usage and user expertise. Second, The valuation and compensation factor affects the user's satisfaction of KMS in case of organization's flexibility, trust, degree of functional provision and user expertise. But it does not affect the user's satisfaction of KMS in case of suitability of knowledge, easiness of usage and perceived benefit.

As Knowledge Management (KM) has taken an essential position of managing businesses in the knowledge-oriented society, many companies have adopted Knowledge Management System (KMS) into their organization. Many have questioned, however, in the result and the effectiveness in KMS. The purpose of this study is to explore ways to improve the current KMS by analyzing and identifying the causes that affect effectiveness of KMS. Blog which is an effective tool for communication could be used for KMS in order to make KMS more user friendly and more effective. This research is intended to conduct an empirical study on the differences between Blog-based KMS and Non-Blog-based KMS and suggest resolutions to potential issues of KMS. Blog-based KMS users show higher degree of satisfaction and usage toward their system. The result of this study suggests that the differences between two groups are primarily on system quality and knowledge quality, and many of these differences come from functions and characteristics of Blog.

This research derived five success factors(the characteristics of system, knowledge, management, organization and users) for knowledge management system(KMS) and empirically analyzed the influence on the performance(usage and user satisfaction) by setting these characteristics to military KMS. This study shows that user characteristic affects most positive(+) effect to usage, and knowledge characteristic affects most positive(+) effect to user satisfaction but organization characteristic affects negative(-) effect to usage and user satisfaction. The result of this research illustrates the successful operation of military KMS and expects the early settlement of the military forces that will establish KMS by reducing initial trial and errors.

This study, centered on public institutions that introduced and are using Knowledge Management System(KMS), is a study of affecting influence factors for utilization and satisfaction. In case of public institutions, they introduced in earnest knowledge management system starting second half of 1999 and most branches of the government such as Department of Defence, Ministry of Government Administration and Home Affairs and Ministry of Planning and Budget have laid the foundation and been managing the system. As a result understanding convenience and need of knowledge management system and awareness for importance of knowledge asset are proliferating. But there is a lot of difference in utilization of KMS by work unit and also can find that the difference exists among users in terms of satisfaction. This is expected as having influence from chief officer's concern, support of exclusively responsible personnel factor, whether education training was given, KM process support etc. for KMS. Therefore this study draws subordinate factors of organization characteristic, knowledge information characteristic, strategy characteristic as influence factors to KMS and analyzes how these subordinate factors influence utilization and satisfaction of KMS to suggest a way to catalyze knowledge management system in the future.

As many companies have recognized the importance of Knowledge Management(KM), they have invested lots of their resources in developing and deploying Knowledge Management Systems(KMS) to organize and share knowledge. When they implemented KMS in their organizations, most of them had high expectations about KMS at tile beginning. However, as time passed, its usage was rapidly declined. There have been many attempts to increase its usage. Many research works have tried to find solutions from users and organizations viewpoints, instead of the actual usage data itself. In order to assess the usage level of KMS, they have normally utilized user's attitudes toward KMS by assuming that user attitudes have strong relationship with actual uses of KMS. The purpose of this study is to assess tile impacts of user, organizational, and job characteristics on the satisfaction and the usage levels of KMS. Unlike other studies, this study is to explore impact factors which affect the usage level of KMS in organizations by using actual KMS log data as well as user's attitudes.

This study introduces the construct of group efficacy and combines the construct with the Adaptive Structuration Theory(AST) and user satisfaction framework. Job efficacy and IT efficacy identified as the dimensions of group efficacy are hypothesized to influence faithfulness of appropriation and consensus on appropriation. and then the user satisfaction of knowledge management systems(KMS). Data were collected through a survey of respondents who have the experience of using KMS, and analyzed by using structural equations modelling. The major findings of this study are as follows: First, job efficacy was found to have a positive influence on consensus on appropriation and user satisfaction. Second, IT efficacy was found to have a positive effect on faithfulness of appropriation and consensus on appropriation. Third, faithfulness of appropriation was found to have a positive influence on consensus on appropriation and user satisfaction. Implications of these findings are discussed for researchers and practitioners.
